water boiler electric 220v round type 11 ltr
Our industry is a big country, provide power for industrial equipment giant multi-water boiler electric 220v round type 11 ltr. After investigation, the vast majority of our country's industrial boilers are in healthy condition, causing energy waste and pollution is very alarming. Moreover, the recent nationwide boiler accidents continue to occur, causing huge casualties and property losses, the adverse impact on society and the economy, how to effectively protect the safe operation of the boiler to be solved throughout the boiler industry event.
First, before regularly shutting down water boiler electric 220v round type 11 ltrs and inspecting electric furnaces, the following three aspects of preparation should be done: The main contents are as follows: (1) consult the technical file of boiler retrofit electric furnace registration and understand the use of boiler retrofit electric furnace. In order to make the boiler reform electric furnace inside and outside inspection, the general need to know: boiler transformation electric furnace design, manufacturing, installation situation; boiler transformation electric furnace transformation situation; boiler transformation electric furnace operation history and use situation; Boiler retrofit electric furnace water treatment, boiler rules and regulations implementation, and so on.
2) the preparation for stopping the furnace before inspection. First, according to the maintenance schedule, the furnace shutdown date is arranged, and then the boiler revamping electric furnace is shut down according to the normal shut-down procedure, so that the furnace is slowly frustrated. The cooling method can be adopted by injecting gas to dissipate the sinking water, replacing the furnace water for cooling, and cooling by ventilation in the in-line furnace. When the temperature of the furnace water drops to 70 ℃ 80 ℃, the water can be discharged. Open all the doors. When opening the door hole, prevent warm water, steam suddenly spurts out to burn people. The steam, feed water and sewage pipes in the furnace are separated from the corresponding pipes in the boiler revamping furnace in operation. The baffle used for partition should be strong enough to avoid being bulged out by high pressure media. Break position Clear instructions should be given. The flue which is connected with other boiler revamping electric furnaces should also be reliably separated. In addition, it is necessary to remove the soot and scale on the heating surface of the boiler retrofit electric furnace.
3) preparation of inspection tools and lighting. In order to ensure smooth inspection work, inspectors should prepare the necessary instruments, tools, gauges and safe and reliable lighting.
What is the cause and solution of running air water in electric water boiler electric 220v round type 11 ltr? Electric boilers need to involve a lot of running air (exhaust valves) in the installation process. Under normal circumstances, do not rush to power up the boiler before installing the boiler must first carry on the cycle test, sometimes the test time will find that the electric boiler gas outlet water, Now let's break down the reasons. This phenomenon is mainly due to the electrical boiler installation error, the circulation pump installed in the electrical boiler inlet. The return water of the electric boiler is larger than the intake. When the return water is larger than the water intake, the countercurrent will be formed, and the natural vents will form bubbles, which is what we usually say is the efflux of gas holes. The solution to this problem is to install the circulating pump in the correct location on the OK.
Steam water boiler electric 220v round type 11 ltr pressure gauge should pay attention to matters 1. The rated steam pressure less than 2.45MPa steam boilers, pressure gauge accuracy of not less than 2.5; equal to the rated boiler steam pressure 2.45MPa, the pressure shall not be less than 1.5. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Dial gauge diameter of not less than 100 mm, to ensure that the operator can clearly see the surface pressure indication. 2. On the dial gauge steam boiler should draw a red line to indicate the maximum allowable working pressure. 3. The steam boiler pressure gauge should be installed in place to facilitate the observation and purged, and should prevent high temperature, vibration and icing. 4. The steam boiler pressure gauge should be checked at least once every six months, to be sealed lead-sealed after calibration. 5. The steam boiler gauge connection tube not leak water and steam, otherwise it will reduce the pressure instruction value. 6. A steam boiler pressure gauge measuring range should be compatible with the operating pressure of the device under test, the working pressure is generally 1.53 times, preferably 2 times the working pressure. Steam boiler no pressure gauge, pressure gauge or pressure gauge damage does not meet the requirements. When the steam boiler pressure gauge of the following circumstances, should stop using: 1. The surface of the glass or the dial pins; Lead seal, lead seal is broken or exceeds the calibration period; when no pressure gauge pointer position is limited to the limit staple nail can not be restored, and the rank unlimited gauge pointer movement from zero data is out of range pressure layer. Poor; leak or pointer jitter in the meter; other defects affect the accuracy of the pressure gauge. The use of the accumulator: the accumulator for a hydraulic system of the machine intermittently. It may be a low speed motion or intermittent motion of the actuator, the oil reservoir of the hydraulic pump, when rapid movement of the actuator requires a large flow rate, as an auxiliary energy supply to the system together with the hydraulic pump, enabling the pump and the entire hydraulic system miniaturization, to achieve energy saving. Hydraulic shock absorber valve and the opening and closing of rapid mutation load, the system generates a pressure shock, loved one causes vibration and noise and even damage the machine. The accumulator can relax and absorb the impact pressure of the liquid. Accumulators absorb and reduce the pressure pulsation flow pulsation and various hydraulic pumps, thus reducing noise and vibration system. The function of the gas spring having a damper, the vibration can be used to walk between the car body and the wheel and other mechanical absorption. The accumulator may be balance gravity vertical actuator (hydraulic cylinder) and the potential energy absorbing load drop into hydraulic energy storage, while producing speed resistance. When the rising vertical actuator, the accumulator absorbs energy of the original release, and together with the oil pump to the hydraulic cylinders, so as to achieve balance and energy.
